Hepatic hemangioma

Discussion:

Hemangiomas are the most common benign tumor of the liver occurring most frequently in women. There is no age predilection. A small percentage presents with calcifications. Peripheral enhancement with centripetal fill-in is classic for hemangioma but may be seen in other tumors.

To conclude that a lesion is a hemangioma on CT, the enhancement must be equal to or greater than that of the aorta, persist with delayed images (enhancement was seen at 10 minutes delay on this study) and show peripheral globular enhancement. MRI is frequently being used to diagnose hemangiomas as signal characteristics can be used in addition to enhancement pattern.
